Abstract: 1,130,105. Boots &c. SEMPERIT OSTERREICHISCH-AMERIKANISCHE GUMMIWERKE A.G. 12 May, 1967 [18 May, 1966], No. 22061/67 Heading A3B. The toecap of a rubber boot or shoe is stiffened by means of a fabric impregnated with a thermosetting synthetic resin e.g. a phenolformaldehyde resin precondensate, urea-formaldehyde resins, mixtures of polyesters or polyethers with polyisocyanates or a styrene-vinyltoluene mixture with added butyl perbenzoate. Glass fibres may also be added to the stiffener. The shoe is made by punching the stiffener from a fabric impregnated with the resin precondensate sewing the stiffener to a lining, assembling the lining and stiffener together with a rubber upper on a last and subjecting the assembly to heat and pressure which vulcanizes the rubber and hardens the resin of the stiffener. The stiffener is particularly suitable for use with shoes having hard rubber toecaps.

Title: Improvements in or relating to dispensing apparatus for liquids
Inventor: HOUSE EDWARD TERENCE
IPC: B67D7/30
Filed: 1961-06-19
Abstract: 937,257. Dispensing liquids. AVERY-HARDOLL Ltd., and SHELL-MEX & B.P. Ltd. June 18, 1962 [June 19, 1961], No. 22074/61. Class 116. [Also in Group XXIX] In a liquid dispensing apparatus the quantity of liquid delivered is preselected by operating an auxiliary valve 36, Fig. 9, in the hose cock 17 to produce pulses of liquid flow in an auxiliary conduit 35, the main flow through conduit 32 being terminated by the closing of a control valve 26, Figs. 2, 3, controlled by flow meter 25 after the delivery of a quantity of liquid proportional to the number of pulses. On pulling down a hose boom an electric pump pressurizes the apparatus and lever 37 is lifted to stop 43 so that valve 36 permits an auxiliary flow at 27 through a device 28 containing a spring-loaded disc which lifts a rod 84 carrying a pawl 88 for moving a ratchet wheel 72 round one notch for each pulse, a rod arm 98 snapping roller 89 on to a toothed wheel 73 to prevent shaft 69 moving backwards on winding up spring 75. After the pulses pawl 41 snaps passed the stem of valve 36 and allows it to close and further movement of lever 37 opens the main delivery valve 33 whereupon liquid flows passed the control valve 47 which is moved slightly towards closed position by pressure acting via floating disc 55 and spring 57, the valve movement being transmitted via cranks 52, 99, 102 to press a cam follower 109 on to a cam 74, and rotate a shaft 103 so that gear 71 engages gear 68, lever 118 snaps roller 89 clear of gear 73 and lever 119 snaps pawl 122 passed a solenoid-operated stop 124 preventing return movement of shaft 103. During the last unit of delivery the flow meter rotates cams 74 so that follower 109 enters slot 80 which permits the control valve 47 to partially close and when the delivery is finished, meter 25 rotates a cam 64 on a counter until a cam follower 106, 108 enters a slot 65 permitting the valve 47 to fully close. On raising the boom the pump is stopped and the solenoid 124 releases lever 119, whereby the valve 47 opens under its weight and rotates shaft 103 to reposition the followers 106, 107 and lever 118, and moves crank 112 to disengage gear 71 from meter-driven gear 68. In an alternative embodiment, the pulse moved ratchet wheel positions a rotary switch which selects a circuit connected to an indicating device driven by the meter. Specification 937,256 is referred to.

Title: Apparatus for releasing flat articles from a stack
IPC: B65G59/06
Filed: 1970-05-07
Abstract: 1356923 Releasing flat articles from a stack MASSON SCOTT THRISSELL ENG Ltd 6 May 1971 [7 May 1970] 22158/70 Heading B8C [Also in Division F2] Apparatus for releasing records, or other flat articles, one at a time from the bottom of a stack BR comprises two sets of movable, stacksupporting, members, the members 329 of one of said sets being simultaneously movable between supporting positions immediately below the stack and release positions clear of said stack and the members 331 of the other set being simultaneously movable between supporting positions between the lowest and next-to-lowest record in said stack and stand-by positions clear of said stack, and drive means for operating said two sets of stack-supporting members in timed sequence so that the members of the two sets are moved alternately. The members 329 of the one set are moved from their supporting positions to their release positions and returned to their supporting positions while the members 331 of the other set remain in their supporting positions, the members 331 of the other set being moved from their supporting positions to their stand-by positions and returned to their supporting positions while the members 329 of the one set remain in their supporting positions. As shown, the apparatus comprises a base-plate 322 which has a window 324 through which the stack of records BR passes and which supports, along each of three sides of the window 324, corresponding escapement mechanisms 325, 326, 327 each of which comprises, as described with respect to escapement 325, Fig. 4A-4D, a lower support plate 328 having two spaced fingers 329 and an upper support plate 330 provided with a single finger 331. The plates 328, 330 are carried by rods 332, 333 which are non-rotatably, slidably, mounted in bearings 334, 335 and are spring-loaded to engage corresponding cam surfaces 337, 338 mounted on a vertical shaft 339. The latter is rotated, one revolution at a time, by a shaft 346 which is connected by a toothed belt mechanism 353 and bevel gearing 348, 349 to a shaft 350 which is driven by a single-revolution clutch 351 (see Division F2) connected to a constant drive unit 152. Belt mechanisms 354, 355 transfer synchronous movements to the escapements 326, 327. As the shaft 350 commences to rotate the stack BR is supported on the fingers 331, and a record, separated from the bottom of the stack, is supported on the fingers 329. Continued rotation of the shaft 350 causes the fingers 329 to retract so that the lowermost record drops on to a blank 320 carried by a chain conveyer 105. The fingers 329 are then advanced as the fingers 331 are retracted so that the fingers 329 support the stack whereupon the fingers 331 are again advanced to support the stack and separate the bottom record from the rest of the stack to complete the cycle of operation. A signal, produced by a photo-cell 376 as a blank 320, moved by the conveyer 105, passes thereby starts the drive of the one-revolution clutch 351.
